Each side plate 97 extends from the end edge and closes the storage space 82 on both sides in the vehicle front-rear direction. As shown in FIGS. 6 to 8, the side plate portions 97 on both sides protrude toward the vehicle interior side at the lower portion on the vehicle interior end side, and on the front end side of the lower end portion of the front plate portion 86 of the lid 80 in the vehicle longitudinal direction. A support portion 101 is formed to rotatably support both ends via a support shaft 100 along the vehicle longitudinal direction. The support shaft 100 and the support portion 101 can turn the lid 80 to the case body 83. A connecting portion 90 to be connected is configured. The lid 80 is engaged with the case main body 83 by a plurality of engaging portions (not shown) in a state where the storage space 82 is closed, and the rotation of the lid 80 is restricted.

  In the first embodiment, the upper plate portion 85 side of the front plate portion 86 of the lid 80 protrudes laterally along the front plate portion 86 from the pedestal portion 103 and the pedestal portion 103 that protrude outward from the passenger compartment. A shaft-like support projection 104 and a flange portion 105 projecting radially outward from the tip of the support projection 104 are formed, and the side plate portion 97 of the case body 83 also extends in parallel with the support projection 104. A shaft-like support protrusion 107 and a flange 108 protruding radially outward from the tip of the support protrusion 107 are formed. Linear straps (regulating means, connecting members, linear bodies) 110 that are easily deformable and do not change in length are hung on the support protrusions 104 of the lid 80 and the support protrusions 107 of the case body 83. . In other words, the strap 110 is connected to the lid 80 by the engagement portion 111 formed in a loop shape on one end side being hung around the support protrusion 104 of the lid 80 so as to go around the support projection portion 104, and the loop 110 is formed on the other end side. The engagement portion 112 formed on the base body 83 is connected to the case main body 83 by being hung around the support protrusion 107 of the case main body 83 other than the lid 80 so as to go around the support protrusion 107. In this way, the opening amount (rotation angle) of the lid 80 with respect to the case body 83 is regulated by stretching the strap 110 that connects the lid 80 and the case body 83. Note that the flange portions 105 and 108 restrict the loop-shaped engaging portions 111 and 112 from coming out of the support protrusions 104 and 107.

  Further, in the first embodiment, the bent portion 115 configured on the close proximity side of the front plate portion 86 and the upper plate portion 85 of the lid 80 protrudes outward of the vehicle compartment, that is, inside the airbag 81 side. However, a plurality of plate-like ribs 116 extending in the vertical direction are formed at intervals in the vehicle front-rear direction. These ribs 116 are formed so as to connect an intermediate position on the opposite side of the upper plate portion 85 to the front plate portion 86 and an intermediate position on the opposite side of the upper plate portion 85 of the front plate portion 86. A guide surface 117 outside the passenger compartment is recessed in a substantially arc shape. These ribs 116 are on the upper side opposite to the lower support shaft 100, which is the center of rotation when the lid 80 is opened, and as shown in FIG. 7, the guide surface 117 is upper when the lid 80 is closed. It inclines so that it may be located in the vehicle compartment outer side. For this reason, when the airbag 81 that is deployed upward in a state where the lid 80 is closed contacts the guide surface 117, the guide surface 117 is separated from the pressing force of the airbag 81 toward the interior of the lid 80, that is, toward the open side. A force is generated, and the lid 80 is favorably opened. Moreover, as shown in FIG. 8, when the lid 80 is opened to the limit position by the strap 110, the rib 116 is substantially along the vertical direction, and comes into contact with the deploying airbag so that the deployment is upward. invite. In other words, the deployment direction is regulated.

  The mounting piece 14 described above is formed in the lower part of the case body 83. As shown in FIG. 5, the inner panel 6 and the inner side reinforcing panel 36 are inserted after the bolt 15 is inserted into the mounting hole 120 of the mounting piece 14. The air bag module 10 is attached to the inner panel 6 by being inserted into the attachment hole 121 formed in the inner side and screwed into a weld nut 122 fixed to the back side of the inner side reinforcing panel 36.

  Since the air bag 81 is folded so as to be sequentially stacked on the upper side with respect to the pipe 76 that is a gas introducing portion, the air bag 81 is basically deployed on the upper side when deployed with the gas generated by the inflator 77. Since the airbag module 10 is attached to the inner side of the inner panel 6 as described above, the airbag 81 is disposed on the inner side of the inner panel 6 and is in a folded state. Sometimes the interior of the vehicle is covered with a lid 80. Here, the airbag 81 has a long shape in the longitudinal direction of the vehicle, and a plurality of non-inflatable portions (not shown) that do not inflate are juxtaposed in the longitudinal direction of the vehicle by weaving such as sewing, bonding, or jacquard weaving. Develop as a plate as a whole.

  In the airbag device 1 described above, the inflator 77 is ignited when a deployment condition such as, for example, a gravitational acceleration of a predetermined value or more is detected at the time of a vehicle collision, and the folded airbag 81 is inflated with gas generated by the inflator 77. To do. Then, since the airbag 81 is folded so as to be sequentially stacked on the upper side, the airbag 81 is deployed so as to extend upward from the lower side of the window 9 as indicated by a two-dot chain line in FIG. Then, the airbag 81 is pushed by the guide surface 117 of the rib 116 that is mainly inclined of the lid 80 during deployment, so that the lid 80 is regulated by the strap 110 around the support shaft 100 so as to exceed the contact tongue 48. After being rotated by the amount, it is guided by the guide surface 117 of the rib 116 of the lid 80 and is developed upward along the inner surface of the window glass 7 of the upper window 9.

  According to the airbag storage portion structure of the first embodiment described above, when the lid 80 that has been pressed by the airbag 81 that is deployed to close the storage space 82 is opened, the strap 110 provided on the lid 80 is removed. The opening amount of the lid 80 is regulated. That is, the strap 110 whose one side is connected to the lid 80 and whose other side is connected to the case main body 83 other than the lid 80 regulates the opening amount of the lid 80. Therefore, it is possible to prevent the lid 80 from narrowing the vehicle interior space more than necessary when the airbag 81 is deployed. In addition, since the lid 80 only connects the lid 80 and the case main body 83 other than the lid 80, the opening amount of the lid 80 can be easily and reliably regulated.

  Further, since the linear strap 110 is used, a space for storing the strap 110 can be reduced.

  Further, when the lid 80 is opened by pressing with the airbag 81 to be deployed, the airbag 81 can be guided by the rib 116 of the lid 80 whose opening amount is regulated by the strap 110 and the deployment direction thereof can be regulated. Therefore, the deployment direction of the airbag 81 can be suitably controlled.

  In addition, the lid 80 is formed with a bent portion 115 on the opposite side to the support shaft 100 that is the rotation center at the time of opening, and the bent portion 115 is provided with a rib 116. Can be prevented from coming into contact with the bent portion 115. Therefore, the airbag 81 can be deployed better.

  Furthermore, since the deployment of the airbag 81 is restricted by the rib 116 extending in the vertical direction on the lid 80, the airbag 81 can also be used as a rib for increasing the rigidity of the lid 80. Therefore, manufacture becomes easy.

  In the above description, the case where the lid 80 is provided in the case 75 that stores the airbag 81 of the airbag module 10 has been described as an example. However, the present invention can be applied to the case where the lid 80 is directly provided on the door lining 8.

  In the above, the case where the strap 110 is hung on the lid 80 and the case body 83 has been described as an example. However, the strap 110 may be hung on the lid 80 and other than the lid 80. For example, the lid 80 and the inner panel 6 It can be hung on the lid 80 or on the lid module other than the case body 83 of the airbag module 10.

Furthermore, in the above description, the airbag housing portion structure provided in the door 2 of the vehicle has been described as an example. However, if the airbag housing portion structure is disposed near the window and deployed along the inner surface of the window, for example, , An airbag storage structure provided below a rear side window of a coupe type vehicle, an airbag storage structure provided below a tailgate window, and a roof side rail on the upper side of the window It can also be applied to the storage structure of the side curtain airbag.
Further, in the above description, the restricting portion has been described as the rib 116. However, if the development can be guided in the upward direction by contacting the airbag, the rib 116 is formed as a planar portion having the same height. May be.

  Next, the airbag housing part structure of the second embodiment of the present invention will be described below with reference mainly to FIGS. 9 to 11 and focusing on the differences from the first embodiment. In addition, the same code | symbol is attached | subjected to the part similar to 1st Embodiment, and the description is abbreviate | omitted.

  In the second embodiment, first, the attachment piece 14 of the case main body 83 of the airbag module 10 extends further downward than in the first embodiment. Moreover, the inner side board part 93 of the case main body 83 is arrange | positioned above 1st Embodiment, As a result, the downward extension board part 94 is also extended upwards.

  Further, the lid 80 of the second embodiment is not supported by the support portion 101 of the first embodiment, but is supported by an intermediate portion of the attachment piece portion 14. That is, the lid 80 of the second embodiment is provided with the inclined plate portion 130 that is inclined and extends so as to be positioned on the outer side of the passenger compartment as it is positioned downward from the lower end edge portion of the front plate portion 86. A metal regulating plate (regulating means, regulating member) 131 is fixed inside the lid 80. As shown in FIG. 10, the restriction plate 131 has an upper plate portion 132 on the upper side and a lower plate portion 133 on the lower side, and a plurality of mounting holes 135 are formed in the upper portion of the upper plate portion 132. A plurality of mounting holes 136 are also formed in the lower portion of the upper plate portion 132. A plurality of bead portions 137 are formed in the lower plate portion 133, and attachment holes 138 are formed between both outer sides of these bead portions 137 and between adjacent bead portions 137.

The inclined plate portion 130 is joined to the outside of the passenger compartment, and in this state, the tip portion of the protrusion 140 is heated and deformed to be fixed to the lid 80. In this state, the restriction plate 131 extends below the lid 80. In addition to such welding, it is also possible to fix the regulating plate 131 to the lid 80 by caulking or the like.

  Then, a bolt 142 having a long shaft length is inserted into a plurality of mounting holes 138 formed in the lower plate portion 133 of the restricting plate 131, and each bolt 142 is engaged with the head portion 143 and the shaft portion 144. The restriction plate 131 and the lid 80 are held on the head 143 side of the bolt 142 by sandwiching the restriction plate 131 with the tool 145. Then, the tip end side of the shaft portion 144 of the bolt 142 is inserted into a mounting hole 146 formed in the mounting piece portion 14 of the case main body 83, and this mounting piece is secured by nuts 147 and 148 screwed to both sides of the shaft portion 144. The part 14 is clamped. As a result, the restriction plate 131 is supported in a state of being separated from the case main body 83 via the bolt 142. In this state, the restricting plate 131 has an extending portion 150 that extends downward from the bolt 142 side, that is, the base end side, which is the support portion of the lid 80, and the extending portion 150 is attached to the case body 83. Opposite the one portion 14 with a predetermined distance.

  According to the airbag storage portion structure of the second embodiment described above, when the lid 80 that has been pressed by the airbag 81 to close the storage space 82 is opened, as shown in FIG. While the locking member 145 is moved from the head portion 143 of the bolt 142, the upper portion is tilted so that the upper portion is moved to the vehicle interior side about the vicinity of the bolt 142. At that time, the lid 80 is provided. The extension portion 150 of the restriction plate 131 moves to the outside of the passenger compartment, but the extension portion 150 abuts against the mounting piece portion 14 of the case body 83 other than the lid, and the tilt of the lid 80, that is, the opening amount. Will be regulated. Therefore, it is possible to prevent the lid 80 from narrowing the vehicle interior space more than necessary when the airbag 81 is deployed. In addition, since the restricting plate 131 is merely brought into contact with the case main body 83 other than the lid, the opening amount of the lid 80 can be easily and reliably restricted. In addition, since the restriction plate 131 has the extending portion 150 that extends from the base end side of the lid 80, the restriction plate 131 does not impair the opening degree of the lid 80.

  Next, the airbag housing part structure of the third embodiment of the present invention will be described below with reference mainly to FIGS. 12 to 14 and focusing on the differences from the second embodiment. In addition, the same code | symbol is attached | subjected to the part similar to 2nd Embodiment, and the description is abbreviate | omitted.

  In the third embodiment, a part of the restriction plate 131 is cut and raised above the restriction plate 131, and the inclined plate portion 155 is inclined so as to be located on the outer side of the passenger compartment, and the upper end edge of the inclined plate portion 155. An engagement plate portion (engaged portion) 157 having an engagement protrusion 156 extending substantially vertically upward is provided, and the case main body 83 has an inner side above the engagement plate portion 157. A claw portion (engagement portion) 160 extending downward from an end edge portion of the plate portion 93 on the vehicle interior side is formed.

  According to the airbag storage portion structure of the third embodiment, when the airbag 81 is deployed, the airbag 81 is pressed so as to move the downward extending plate portion 94 of the case body 83 toward the vehicle interior side. The lid 80 that has closed the storage space 82 is pressed to open, but when the downwardly extending plate 94 is pressed, the engaging plate 157 of the regulating plate 131 joined to the lid 80 is engaged with the claw of the case main body 83. As a result of the engagement of the portion 160, the engagement plate portion 157 comes into contact with the claw portion 160 and restricts the subsequent tilting, that is, the opening amount of the lid 80. Therefore, it is possible to prevent the lid 80 from narrowing the vehicle interior space more than necessary when the airbag 81 is deployed. Moreover, since the engagement plate portion 157 of the restriction plate 131 is merely brought into contact with the claw portion 160 of the case body 83 other than the lid, the opening amount of the lid 80 can be easily and reliably restricted. In addition, since the restricting plate 131 includes the engaging plate portion 157 that engages with the claw portion 160 provided in the case main body 83 that stores the airbag 81, the amount of opening of the lid 80 is more reliably restricted. Can do.
